You can look up the function in the globals() dict, or you can import 
__main__, which is the top-level module, and use getattr() on it. Or you 
could wrap your functions in a class...

def OnMenuFindMe():
    print 'You found me'

f = globals()['OnMenuFindMe']

f()

import __main__

g = getattr(__main__, 'OnMenuFindMe')
g()
